Yeah, gcc can't do much more since it only handles one source file at a
time. However, the linker certainly deduplicates strings across

If the no_hash_pointers command line parameter is set, then
printk("%p") will print pointers as unhashed, which is useful for

vsprintf, such as print_hex_dump() and seq_buf_printf().
